Li-ion / 18650 7.4V 2-Cells Battery Charger Protection PCB Board (up-to 8-Amps Current)

This Li-ion / 18650 battery protection PCB protect a Li-ion / 18650 batteries with 8A continuous current. Protection is critical as a Lithium-ion batteries could explode when they are shorted circuit or overcharged, and damaged when they are over discharged.

Features

• Over charging - Disconnect circuit when either battery is over 4.35V
• Over discharging - Disconnect circuit when either battery is lower than 2.7V
• Short curcuit protection - Disconnect when short circuit is detected
• High-accuracy voltage detection circuit
• Built-in three-stage over-current detection circuit (over-current 1, over-current 2, or load short circuit)
• MOS transistor can control the battery charge and discharge
• Low standby current consumption
